Ideally you will never pay more than 4% per year on any credit card debt.
This means you pay it off in full, and on time, every month. Or you have done a Balance Transfer or Money Transfer deal. This usually means you’re paying 0% interest for 9, 15 or even 36 months! And the fee they charge for this is often 2.9%, which is incredibly low, especially when spread across 3 years!
If you currently pay more than £25 per month in interest payments on any one card, or combined across several cards, you can save that money if you learn a few key concepts.
